FIGURE 30.1 The Evans classification of intertrochanteric fractures. In stable fracture patterns, the posteromedial cortex remains intact or has minimal comminution, making it possible to obtain and maintain a reduction. Unstable fracture patterns, conversely, are characterized by greater comminution of the posteromedial cortex Basic Anatomy An intertrochanteric fracture is a type of hip fracture or broken hip. The hip is made up of two bones—the femur, or thigh bone, and the pelvis, or socket. The hip is an important ball-in-socket joint that allows you to move your leg when walking. Hips that break between the bone bumps at the top of the thigh bone are said to have broken in the intertrochanteric area of the.

Type 2: impaction fracture, i.e. inversion and adduction of neck fragment with varus collapse of the fracture Type 3 : diatrochanteric fracture, i.e. fracture line extending subtrochanterically or being reversed Tronoo's System (1973) Type 1 : incomplete fracture only involving greater trochante Fracture implant selection for intertrochanteric femur fractures is determined by fracture stability. The Evans classification describes fracture patterns as stable or unstable, based on the integrity of the posteromedial bony cortex. The sliding hip screw is the most widely used device for both stable and unstable fracture patterns InterTrochanteric Fractures 1. INTERTROCHANTERIC FRACTURE Dr. Kevin Joseph Ambadan 2. DEFINITION • An InterTrochanteric fracture occurs between the greater trochanter, where the Gluteus Medius and Minimus muscles (hip extensors and abductors) attach, and the lesser trochanter, where the Iliopsoas muscle (hip flexor) attaches .. Classification. Fractures in these regions can be classified as: intertrochanteric fracture; pertrochanteric: intertrochanteric, involving both trochanters; subtrochanteric fracture; greater trochanteric avulsion fracture An intertrochanteric fracture is a specific type of hip fracture. Intertrochanteric means between the trochanters, which are bony protrusions on the femur (thighbone)
Haentjens P et al. Survival and functional outcome according to hip fracture type: a one-year prospective cohort study in elderly women with an intertrochanteric or femoral neck fracture. Bone. 2007;41(6):958-64. PMID 1791361 Intertrochanteric fracture. There is a fracture from the greater (red arrow) to the lesser (green arrow) trochanter. A lucency, representing the fracture, runs between the two trochanters (white arrows). · Classification - Garden Classification. o The most commonly used classification system for femoral neck fractures is some variation of.
Fracture classification The proximal femoral fractures are classified as 31 fractures. Intertrochanteric Neck and head hip fractures fractures Examples of treatment 31-A with DHS 31-B and C with hemiarthroplasty We will further discuss the 31-A fractures. There are severa Background: A new AO classification for intertrochanteric fractures was recently published; no studies have evaluated its inter- and intra-observer agreement. Methods: Six evaluators (three hip subspecialists and three residents) assessed radiographs of 68 intertrochanteric fractures; fractures were classified using the original and the new AO classifications The lateral wall thickness threshold value for risk of developing a secondary lateral wall fracture was found to be 20.5 mm. To our knowledge, this is the first study to investigate the risk factors of post-operative lateral wall fracture in intertrochanteric fracture Dr. Ebraheim's educational animated video describes proximal femur intertrochanteric fractures and fixation. Intertrochanteric Hip Fracture occurs in the reg..
Intertrochanteric fractures (31A3) require anatomic reduction in both the AP and lateral views. 10 This reduction may be difficult to achieve in certain types of these fractures. Percutaneous insertion of a Steinmann pin, mounted in a T-handle, and open reduction of fragments through a short incision are useful techniques. 27 When reducing trochanteric fractures, possible malrotation of the. The Garden classification of subcapital femoral neck fractures is the most widely used. It is simple and predicts the development of AVN 1,2.Garden described particular femoral neck and acetabular trabeculae patterns which can assist in recognizing differences within this classification system 2.. Garden stage I: undisplaced incomplete, including valgus impacted fractures
The key criterion of any robust classification is whether the fracture can be considered stable or unstable. Presentation Intertrochanteric fractures are often seen in frail older people after low energy falls (ie, from a standing height) A 5-fragment fracture was detected in two cases (2.1%). Using this fragment-based classification system, intertrochanteric fractures can be evaluated in more detail than is possible using conventional classification systems. J. Med. Invest. 66 : 362-366, August, 2019. PMID: 3165630 Boyd and Griffin Classification of Intertrochanteric Fractures Type Description; 1: Simple fracture that extend along the intertrochanteric line from the greater to the lesser trochanter: 2: Comminuted fractures, the main fracture being along the intertrochanteric line, but with multiple fractures in the cortex:
The current study suggests that the AO classification system with groups can be used more reliably to measure intertrochanteric fractures of the proximal femur than Evans, Kyle, and Boyd. Unaware of the daily treatment practice of unstable intertrochanteric fractures in Germany, we conducted a national survey of practicing chairpersons to clarify current opinion and practice, according to geographic and hospital level criteria, in (1) using the established classification systems defining criteria for fracture instability, (2. Fracture stability (the ability of the fracture pattern to resist deformation of weight-bearing) assists in the uncomplicated healing of the fracture. In addition, postoperative care and rates of complications, including mortality and morbidity, vary for the different subcategories of intertrochanteric fractures The diagnosis of an intertrochanteric fracture is confirmed by the review of appropriate radiologic images, including an anteroposterior (AP) pelvic view, an AP view of the involved hip, and either a cross-table lateral view of the hip or a frog lateral view of the hip, as well as a traction AP hip radiograph if the surgeon does not fully understand the fracture pattern

AIM: The aim of this study was to evaluate the trochanteric fracture line in terms of the fracture line angle and anatomical location. METHODS: The preoperative AP radiographs of 164 randomly selected patients with trochanteric fractures were obtained.Measurements were made of: (1) the angle between the mid-shaft femoral axis and the fracture line, (2) the intersection point of the fracture. Hip fractures are classified according to their anatomical location as intracapsular, which involves the femoral head and neck, and extracapsular, which includes intertrochanteric, trochanteric, and subtrochanteric fractures.A low impact fall is the typical mechanism of injury in the eldery and is often associated with underlying osteoporosis.Motor vehicle accidents are typical in younger.
This Evans classification breaks down intertrochanteric femur fractures based on displacement, number of fragments and the type of fragment displaced. Type I is a 2 part fracture, Type II are 3 part fractures and Type III are 4 part fractures The stability of an intertrochanteric fracture is defined by the amount of contact between the proximal and distal main fragments (see the images below). A two-part fracture is very stable because.
Therefore, this study was designed to evaluate inter-observer and intra-observer reliability of the AO-2018 intertrochanteric fracture classification.

FORE 2016 Current Solutions in Orthopaedic Trauma. Hip fractures are classified as femur neck fractures, intertrochanteric fractures, or subtrochanteric fractures according to the fracture site. Femoral neck fractures are classified according to the anatomical location of the fracture and the extent of displacement The image is from a woman aged 65 years who sustained an intertrochanteric hip fracture after falling to the floor (AO Foundation/Orthopaedic Trauma Association classification 31-A2, indicating comminuted fracture involving the lateral cortex)
Due to advances in healthcare, the elderly population is increasing worldwide. The incidence rate of hip fractures is also expected to increase to over 6 million fractures per year by the year 2050 .This likely increase in hip fractures includes femoral neck fractures and intertrochanteric fractures (ITFs) .The mortality and morbidity in patients with ITFs are significantly higher than in. The accuracy of intertrochanteric fracture classification is important; indeed, the patient outcomes are dependent on their classification. The aim of this study was to use the AO classification system to evaluate the variation in classification between X-ray and computed tomography (CT)/3D CT images. Then, differences in the length of surgery were evaluated based on two examinations Trochanteric fracture is a fracture involving the greater and/or lesser trochanters of the femur.. Classification. Fractures in these regions can be classified as: intertrochanteric ; pertrochanteric: intertrochanteric, involving both trochanters; subtrochanteric; greater trochanteric avulsion fracture mography data from a series of surgically treated patients. Methods: In this study, 504 patients with intertrochanteric fractures were retrospectively analyzed. Fracture patterns were graded according to Arbeitsgemeinschaft für Osteosynthesefragen (AO) classification. Fracture lines were transcribed onto proximal femoral templates and graphically superimposed to create a compilation of. Intertrochanteric Fracture. This fracture occurs between the neck of the femur and a lower bony prominence called the lesser trochanter. The lesser trochanter is an attachment point for one of the major muscles of the hip. Intertrochanteric fractures generally cross in the area between the lesser trochanter and the greater trochanter
Classification: Description: Notes: Subcapital: intracapsular: Transcervical: intracapsular: Basicervical: Functionally extracapsular: Intertrochanteric: Extracapsula . Over 65,000 hip fractures each year are recorded in the UK and they are becoming increasingly frequent due to an aging population.. The mortality of a femoral neck fracture up to 30% at one year; consequently, these fractures require specialist care and, indeed, most orthopaedic units now have dedicated. Comminuted fractures, the main fracture being along the intertrochanteric line, but with multiple fractures in the cortex 3 Fractures that are basically subtrochanteric with at least one fracture passing across the proximal end of the shaft just distal to or at the lesser trochanter Fracture classification Will be discussed are the AO/OTA Fracture and dislocation classification Garden's classification AO/OTA Fracture and dislocation classification The proximal femoral fractures are classified as 31 fractures. Intertrochanteric Neck and head hip fractures fractures Examples of treatment 31-A with DH
Classification. Most classification systems for intertrochanteric fractures have poor reliability and reproducibility. A simplified system to aid in evaluating treatment algorithms when assessing the literature is based on fracture stability, which is related to the condition of the posteromedial cortex Intertrochanteric fractures (type 31 A3 following the OTA/AO classification) [10, 11] have unique anatomic and mechanical characteristics and have been traditionally considered unstable [13, 14]. The OTA/AO type 31 A3 fractures are characterized by having a fracture line exiting the lateral femoral cortex distal to the vastus ridge [ 15 ] Preparation of fracture models According to the new AO classification of 31A1 and A2 fracture models of intertrochanteric fractures, the fracture models were simulated. The horizontal line was made 3 cm below the innominate tubercle of the greater trochanter. At the intersection between this horizontal lin intertrochanteric fracture The intertrochanteric region is the region between greater and lesser trochanter which consists of dense trabecular bone and is the site of insertion of many major muscles. The incidence of intertrochanteric fractures varies from country to country
Intertrochanteric fractures are classified as stable or unstable, taking into account fracture morphology and involvement of the posteromedial calcar. The purpose of this study is to determine whether IT fracture stability can be used as a marker for general health or as a predictor of postoperative medical complications in elderly patients The incidence of intertrochanteric hip fracture is expected to increase as the global population ages. It is one of the most important causes of mortality and morbidities in the geriatric population .Reverse oblique and transverse intertrochanteric fractures are classified as AO/OTA 31-A3 according to the Orthopaedic Trauma Association classification system  Patients with Type A31A2 and A31A3 (unstable intertrochanteric femur fracture) as per AO classification and age more than 50 years were included. Patients with a stable type of fracture, expired before final follow-up, less than 50 years, and previous implant in the injured hip were excluded Displaced intertrochanteric fracture of right femur, subsequent encounter for open fracture type I or II with routine healing.

Intertrochanteric fracture classification. This classification, included fractures from the extracapsular part of the neck to a point 5 cm distal to the lesser trochanter. Type 1: Fractures that extend along the intertrochanteric line. Type 2: Comminuted fractures with the main fracture line along the intertrochanteric line but with multiple. The AO/OTA classification of intertrochanteric fractures is designated as 31-A. It is further divided based on stability and fracture pattern. 31-A1 is a stable intertrochanteric fracture, and 31-A2 is an unstable intertrochanteric fracture, while 31-A3 is a reverse obliquity fracture or fractures that involve the lateral cortex
The fracture line of an intertrochanteric fracture runs along the base of the femoral neck between the trochanters, whereas in a pertrochanteric fracture, the line involves both trochanters, one or both of which, may be fractured or separated. Effectively, the pertrochanteric fracture is often, a comminuted fracture and is less stable than an. Several classification systems have been used to assess and manage intertrochanteric fractures, including Evans classification, Jensen classification, Boyd-Griffin classification, Kyle classification, and Arbeitsgemeinschaft für Osteosynthesefragen (AO)/Orthopaedic Trauma Association (OTA) classification [8,9]; the AO classification is the. Classification •Many existing classification schemes —stable —Unstable —More common —⇑age —⇓bone density. 6/5/2018 3 O •Reverse oblique or transverse fracture pattern •Intertrochanteric with subtrochanteric extension. 6/5/2018 8 Lateral femoral wall is defined anatomically as the lateral femoral cortex distal to the. An unstable intertrochanteric fracture of the hip is a fracture that has the potential to displace or result in nonunion despite what appears to be adequate reduction and internal fixation These fractures are common among older adults and can be related to osteoporosis. This type of fracture may cause a complication because the break usually cuts off the blood supply to the head of the femur which forms the hip joint. Intertrochanteric hip fracture: An intertrochanteric hip fracture occurs three to four inches from the hip joint.
Early accurate classification is critical, since the rare isolated greater trochanteric fracture can be treated conservatively, but incomplete intertrochanteric fractures are most often treated with surgical fixation, similar to other intertrochanteric fractures (63,64) Lichtblau S.
